Add informational args to release checks

Pass extra informational strings to check_for_gh_release calls to surface release-specific notes. Updated ct/immich.sh (notes for Immich and VectorChord releases), ct/opencloud.sh (note for OpenCloud), and ct/plant-it.sh (note about web frontend presence). These messages clarify testing/compatibility expectations when checking/releases.
